Recognize nested subscripts in interpolation.
Thanks to Andy Lester for finding this, which actually manifested in
Perl-Critic-Policy-Variables-ProhibitUnusedVarsStricter. The problem is
that the actual heuristics for finding the end of an interpolation are
undocumented, and I missed this rather-obvious case.
Add \b{g} (= \b{gcb})

0.037_02 2015-03-01 T. R. Wyant
Make \b{foo} into an unknown token (and therefore an error. This
applies to \b{anything}, where 'anything' is anything bur 'gcb',
'wb', or 'sb'.
0.037_01 2015-02-25 T. R. Wyant
Handle the boundary assertions introduced in Perl 5.21.9: '\b{gcb}'
(grapheme cluster boundary), '\b{wb}' (word boundary), '\b{sb}'
(sentence boundary), and the corresponding '\B{...}' constructions.
Similar-looking things like '\b{foo}' are not recognized as
assertions, and end up being literals. This is less general than I
usually make things, but was done against the possibility that
(e.g.) '\b{foo}' might be introduced later, requiring
perl_version_released() to return a different number. Any of these
retracted prior to Perl 5.22.0 will simply be removed from
PPIx::Regexp.
---------------------
0.037 2014-11-12 T. R. Wyant
Have PPIx::Regexp::Structure::RegexSet POD recognize that the Perl
docs (specifically perlrecharclass) now call this construction
Extended Bracketed Character Classes, not sets.
0.036_01 2014-11-04 T. R. Wyant
Correctly mark the replacement portion of s///ee as code. Prior to
this release it was parsed as though no /e were present.
Make available the number of times a given modifier is asserted
(except for the match semantics modifiers which get handled
differently). See PPIx::Regexp::Token::Modifier->asserted() and
PPIx::Regexp::Tokenizer->modifier() for details.
0.036 2014-01-04 T. R. Wyant
Retract the "Allow non-ASCII white space under /x" change introduced
in version 0.033. I misread perl5170delta, and implemented early.
Change to explicit character class to recognize white space under /x.
I was previously using \s, which matched too much.
Thanks to Nobuo Kumagai for finding and reporting this.
0.035 2013-11-15 T. R. Wyant
Properly handle multi-character modifiers like /ee. We now handle /eie
as being the same as /eei. Thanks to Anonymous Monk for finding
this.
Properly handle \g and \k back references that do not correspond to an
actual capture group. They are now reblessed into the unknown token,
and counted as errors. Thanks to Anonymous Monk for finding this.
Add method error() to PPIx::Regexp::Element. This should return an
error message when the element is in error -- normally when it has
been blessed into the unknown token or structure.
Add method modifier_asserted() to PPIx::Regexp::Element. This walks
the parse tree backward to determine if the given modifier is in
effect for the element.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.

Have PPIx::Regexp::Token::Code (and offspring) become
PPIx::Regexp::Token::Unknown inside a regex set.
0.030 2013-01-22 T. R. Wyant
Add Regex Sets, which were added to Perl as an experimental feature in
5.17.8. This is experimental in Perl, therefore the parse may
change.
Ditch PPIx::Regexp::Token::GroupType method __expect_after_match() in
favor of the more general __match_setup(). This is done without
deprecation because __expect_after_match() was documeted as
package-private, but noted in the change log because it _was_
documented.

Add method unescaped_content() to PPIx::Regexp::Element().
Rewrite the tokenizing code in PPIx::Regexp::Token::GroupType and
offspring to use regular expressions specific to the regexp
delimiter, and escaping only that delimiter. Thanks again to
Alexandr Ciornii for finding more of these.
0.028_01 2012-12-20 T. R. Wyant
Fix mis-parse of /(\?|I)/ as a branch reset (it's really an
alternation). There may be more of these lurking. Thanks to Alexandr
Ciornii for finding this one.
Add options -files and -objectify to eg/predump.
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.

0.025 2012-01-04 T. R. Wyant
Tolerate leading and trailing white space around the regular
expression. These are still round-trip safe, since the white space
is tokenized.
Make Changes file conform to CPAN::Changes, and add
xt/author/changes.t to ensure continued compliance.
0.024 2011-12-17 T. R. Wyant
Reinstate author test xt/author/manifest.t, which was clobbered
shortly before the release of 0.021_10.

Correct address of FSF in the version of the GPL distributed in
LICENSES/Copying. Thanks to Petr Pisar for picking this up.
0.022 2011-11-24 T. R. Wyant
Correct various documentation errors.
The default-modifier functionality is no longer considered
experimental.
No code changes since 0.021_11.
0.021_11 2011-11-15 T. R. Wyant
Don't initialize effective modifiers with '^', since that wrongly
asserts that /d has been seen somewhere along the line.
Implement negation of match-semantic modifiers (e.g. 'no re /u;') by
setting the relevant datum to undef.
THE DEFAULT-MODIFIER FUNCTIONALITY IS EXPERIMENTAL, AND MAY BE CHANGED
WITHOUT NOTICE until the next production release.
0.021_10 2011-11-14 T. R. Wyant
Support for default modifiers. This includes:
* default_modifiers argument to new() in PPIx::Regexp,
PPIx::Regexp::Tokenizer, and PPIx::Regexp::Dumper
* Public method modifier_asserted() on PPIx::Regexp, to return
whether a given modifier is actually in effect. The results of the
modifier() method are unchanged.
THIS FUNCTIONALITY IS EXPERIMENTAL, AND MAY BE CHANGED OR REVOKED
WITHOUT WARNING.
Require Test::More 0.88 for installation. Eliminate all the 'eval
{ require ... }' logic in favor of 'use Test::More 0.88'.
Have Makefile.PL make use of {BUILD_REQUIRES} if it is available.
Fix PPIx::Regexp::Token::Whitespace->can_be_quantified() to return
false.
0.021 T. R. Wyant 22-Jul-2011
Modified tokenizer to correctly handle a back slash used as a
delimiter. I believe.
PPIx::Regexp::Dumper now dumps the results of ppi() if that method is
present and -verbose is asserted.
0.020 T. R. Wyant 02-Apr-2011
Corrected perl_version_introduced():
\R is now 5.009005 (was 5.000).
0.019 T. R. Wyant 01-Mar-2011
Various corrections to perl_version_introduced():
\X is now 5.006 (was 5.000);
\N{name} is now 5.006001 (was 5.006);
\N{U+xxxx} is now 5.008 (was 5.006).
The \C is now parsed as a PPIx::Regexp::Token::CharClass::Simple. It
was previously considered a PPIx::Regexp::Token::Literal.
Ensure that \N{$foo} parses as a Unicode literal, not a quantified \N.
The ordinal() method returns undef for this.
Understand the /aa modifier, introduced with 5.13.10.
Report perl_version_introduced() of 5.013010 for the new semantic
modifiers when modifying the entire expression.
Correct handling of interpolations like ${^foo} and $#{foo}.

No changes (other than version) since 0.017_02.
0.017_02 T. R. Wyant 31-Jan-2011
Override ppi() in PPIx::Regexp::Token::Interpolation to provide the
proper PPI when variable names are bracketed.
Properly parse bracketed variable names (I hope!), which may not be
subscripted.
0.017_01 T. R. Wyant 28-Jan-2011
Take account of possible '$' or '@' casts before a symbol in an
interpolation (e.g. $$foo{bar}, which is equivalent to $foo->{bar}).
0.017 T. R. Wyant 26-Jan-2011
Add the /a modifier to PPI::Regexp::Token::Modifiers, legal only in
the (?:...) construction. This was introduced in Perl 5.13.9.
When parsing an interpolation from a replacement string (rather than a
regular expression), take subscripts at face value rather than
trying to disambiguate them from quantifiers and character classes,
which they can't be in this context.
0.016 T. R. Wyant 05-Jan-2011
The PPIx::Regexp::Token::Code perl_version_introduced() method now
returns the minimum Perl version (currently set to 5.000) if it is
used to represent the substitution portion of s///e.
Update copyright to 2011.
0.015 T. R. Wyant 25-Oct-2010
Documented intent to revoke support for features introduced in a
development Perl which do not make it to a production release. This
is necessary because in this case the syntax could be reused with
different semantics.
Added support for Perl 5.13.6 (?^...) construction.
Added support for Perl 5.13.6 d, l, and u modifiers.
Fixed inconsistency in perl_version_introduced() results between
PPIx::Regexp::Token::Modifier and
PPIx::Regexp::Token::GroupType::Modifier.
Corrected PPIx::Regexp::Constant RE_CAPTURE_NAME docs, somehow missed
back at 0.010_01.
0.014 T. R. Wyant 14-Oct-2010
Recognize \o{...} as a PPIx::Regexp::Token::Literal, with
perl_version_introduced() of 5.0013003.
Terminate \0.. through \7.. after three characters, as Perl does.
These two were brought to my attention by Brian D. Foy's "The
Effective Perler" for October 11 2010,
http://www.effectiveperlprogramming.com/blog/697
Correct the PPIx::Regexp::Token::Literal ordinal() method for '\b'. As
a literal, this is a back space.
0.013 T. R. Wyant 10-Oct-2010
Declare a parse failure if characters are found between the '}' and
the ')' of (?{...}) and (??{...}), and rebless the tokens to
::Unknown. Perl does not accept anything here, so I think I should
not either.
Whitespace tweak in the PPIx::Regexp::Dumper test output for the
failures test.
Replace the PPI logic in PPIx::Regexp::Token::Code with a call to
$tokenizer->find_matching_delimiter(). This is actually the way Perl
works, as a look at toke.c and regcomp.c makes clear.
Push the perl_version_introduced() back to 5.0 at the request of
Alexandr Ciornii, for the potential benefit of Perl::MinimumVersion.
This was done mostly by reading the various perlre, perldelta, and
perlop documents, so these should be taken with a HUGE grain of
salt.

Track all the features reported as introduced (or removed) in Perl
5.010 back to Perl 5.009005, and report them as such.
Report modifier /r as having been introduced in Perl 5.013002, rather
than the default of 5.006.

Remove dependencies on Params::Util and Readonly. The latter involved
changing the symbols exported from PPIx::Regexp::Constant, but these
were documented as private, so ...
Parse POSIX character classes [=a=] and [.a.] as
PPIx::Regexp::Token::CharClass::POSIX::Unknown, which counts as a
parse failure since these are not supported by Perl.
Make the PPI::Document created by PPIx::Regexp::Token::Code->ppi() be
read only. This means we need PPI 1.116. Cache the document, and
ensure the cached result is returned on subsequent calls.

The list of packages is computed by finding all packages which end

Recognize s/.../.../ee as being different from s/.../.../e. In
particular, the replacement portion of the former is _not_ a Perl
expression: it's an interpolatble string, which later gets
eval{}'ed.
scheduled update of devel/p5-Perl-Critic to 1.108.
The purpose of the PPIx-Regexp package is to parse regular expressions
in a manner similar to the way the PPI package parses Perl. This class
forms the root of the parse tree, playing a role similar to PPI::Document.
